Hi I was looking to step up my MG head to a JCM and I was curious to know which is more suitable for me. I was thinking either the 800 or the 900 (probably the dual reverb). I need a pretty versatile sound, with a nice clean but more importantly a heavy crunch. I'm mostly into harder indie bands and 90s grunge, though theres a good range between. To get an idea some of my favorites would be Brand New, Thrice, Nirvana, Manchester Orchestra, Taking Back Sunday, Say Anything, Stone Temple Pilots, Smashing Pumpkins, Foo Fighters, and Metallica. If you could give me some insight on this I'd sincerely appreciate it. Thanks.
